This technical report introduces the recoverable wrapper token (RWT) as a configurable mechanism designed to enhance the security of ERC20 tokens against theft, hacks, and accidental transactions. The RWT allows users to recover lost or stolen assets within a specified recovery window, typically 24 hours. The paper outlines the fundamental principles of the RWT, building upon the ERC-20R framework, which provides a structured approach for asset recovery. It details the configurable features of the RWT, including the ability to set the length of the recovery window and the transferability of unsettled tokens. The report also presents the interface necessary for interoperability with existing ERC20 applications, ensuring that RWTs can be integrated seamlessly into current blockchain systems. Additionally, the authors provide examples of configuration sets and discuss related work that supports the development of recoverable tokens. Overall, the report serves as a comprehensive guide for developers and users interested in implementing RWTs in their blockchain applications.
